摘要/Abstract

摘要： 本研究以尾巨桉纯林(PP)以及尾巨桉分别与格木(EE)、降香黄檀(ED)、红锥(EC)和望天树(EP)营建的混交林为对象,研究0～20 cm土层土壤磷组分、土壤理化性质、优势树种尾巨桉细根性状、微生物生物量和胞外酶活性特征及其相互关系,并分析了营建尾巨桉人工混交林对土壤磷组分的影响机制。结果表明:与PP相比,EE和EC土壤活性磷含量分别显著提高77.7%和28.2%,中等活性磷含量分别显著提高25.4%和13.4%;ED中等活性磷含量显著提高24.2%,EP活性磷含量显著提高44.3%。此外,与PP相比,EE和EC土壤有机碳含量、微生物生物量碳和碳氮获取酶活性均显著提高;ED土壤铵态氮和硝态氮含量显著提高,碳氮获取酶活性显著降低;EP土壤全氮含量与碳氮获取酶活性均显著降低。营建混交林促使土壤酸性磷酸酶活性提高24.7%～43.5%。随机森林分析表明,微生物生物量碳、尾巨桉细根磷含量、根表面积和N-乙酰-葡萄糖苷酶是土壤活性磷与中等活性磷的主要影响因子。结构方程模型表明,混交模式通过调控优势树种尾巨桉细根性状和土壤微生物代谢特征,进而影响土壤磷组分含量及有效性。综上,在桉树人工林生态系统中,尾巨桉-格木和尾巨桉-红锥混交林在提升土壤磷有效性方面优势显著。

Abstract: We investigated pure Eucalyptus urophylla × E. grandis plantations (PP) and their mixtures with Erythrophleum fordii (EE), Dalbergia odorifera (ED), Castanopsis hystrix (EC), and Parashorea chinensis (EP), and studied soil phosphorus (P) fractions, soil physicochemical properties, fine-root traits of the dominant E. urophylla × E. grandis, microbial biomass, and extracellular enzyme activities in the 0-20 cm layer, as well as their interrelationships. We analyzed the mechanisms underlying the effects of mixed plantations of E. urophylla × E. grandis on soil P fractions. The results showed that, compared with PP, EE and EC significantly increased labile P by 77.7% and 28.2%, moderately labile P by 25.4% and 13.4%, respectively. ED significantly increased moderately labile P by 24.2%, whereas EP significantly increased labile P by 44.3%. Furthermore, compared with PP, EE and EC had significantly higher soil organic carbon, microbial biomass carbon, and activities of C- and N-acquiring enzymes. ED significantly increased soil ammonium and nitrate, accompanied by a significant decline in C- and N-acquiring enzyme activities. EP exhibited significant reductions in both soil total nitrogen and the activities of C- and N-acquiring enzymes. Mixed plantations increased acid phosphatase activity by 24.7%-43.5%. Random forest analysis indicated that soil microbial biomass carbon, fine-root P content and root surface area of the dominant E. urophylla × E. grandis, and N-acetyl-β-glucosaminidase were the primary drivers of labile and moderately labile P. Structural equation modeling indicated that mixed plantations influenced the content and availability of soil P fractions by modulating fine-root traits and soil microbial metabolic traits. Overall, our results indicated that establishing EE and EC mixtures represented particularly effective strategies for improving soil P availability in Eucalyptus plantations.

Key words: mixed plantation, soil phosphorus fraction, root trait, microbial biomass, enzyme activity
